SASH' FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 396,150, dated January15, 1889. Application filed March 12, 1388. Serial No, 267,034- (Nomodel.)

To all whom it may con/cent.-

Be it known that I, JOHN G. ERICKSON, of Hadley, in the county of Murrayand State of Minnesota, have invented a new and Improved Sash Lock andFastener, of which the following is a full, clear, and exactdescription.

My invention relates to a sash lock and fastener, and has for its objectto provide a device automatic in its action, strong and durable, freefrom springs, simply attached, and which will hold the sash at anydesired height, and lock the same when closed without possibility of itsbeing pried open from the outside.

The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of the device applied to a window-sash.Fig. 2 is a longitudinal section through the same, illustrating theparts in position to lock the window when closed; and Fig. 3 is asimilar view illustrating the position of the parts when the window isheld open.

In carrying out the invention the casing A is provided with a partialopening, a, in one side, extending from a point near the lower end tothe top, and the wall below the said opening upon the inner side is madeto incline downward, as illustrated at a. in Fig. 2.

\Vithin the casing'an angular gravity-bolt, H, is pivoted, the upperarm, which is the longer, being provided with an outwardlyprojectinghead, Z). By reason of the long upper member of the bolt it naturallyassumes a position illustrated in Figs. 1 and 2, the

head extending from within the casing through the opening a. In order tothrow the said long arm back into the casing, a slot, D, is cut in theface of the casing,intersecting the opening a. and extending downward atan I inclination parallel with the wall-surface a, as shown in Figs. 2and f3, and within the easing a disk, D, having a serrated or otherwiseroughened exterior, is manipulated from the outside by means of aspindle, d, integral with the disk, which spindle, projecting throughthe slot D, is provided with a suitable knob or handle,E. The casing ispreferably open at the back.

In operation the device is attached to the side of the window-sashflush, or nearly so, with the inner edge, as shown in Fig. 1, being heldby two screws, 6 6, only, one acting as a fulcrum for the angle-bolt andthe other serving as a stop, limiting the inner throw of the bolt.

\Vhen the devices are in the position shown in Fig. 2, the frictionholder or disk D serves to hold the upper end of the bolt B projectedthrough the casing-opening a into the recess II, and the sash is thuspositively locked against upward movement. To retract the bolt, thefriction-holder D is moved upwardly until it strikes the bolt above itspivot. The sash may now be raised to any desired position, and theoperator holds the handle E with the right hand and allows the sash tolower slightly. This will cause the friction-holder to ride up theincline formed by the upper arm of the bolt until it is firmly wedgedbetween the sashway and said upper arm, as shown in Fig. 3, and thus asash-holder is formed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

I. A combined sash fastener and holder, consisting in a casing having anopening in one side, an inclined locking-bolt within the casing andprojecting, when thrown through said opening, to positively lock thesash when closed, a vertically and outwardly movable friction-holder,also in said casing in front of and below the bolt, whereby, when movedvertically, said friction-holder will retract and ride up said inclinedbolt and be forced simultaneously outward thereby through the saidopening in the casing to hold the sash open,

substantially as set forth.

2. A sash-fastener comprising a casing having a side opening and adownwardincline in the lower end of said casing, a bolt pivoted betweenits ends in said casing, and a disk working on said incline and againstthe lower end of said bolt to hold its upper end projected through thecase-opening, substantially as set forth.
